STONE-SCREENIN GS DISTRIBUTER.

Specification of Letters Patent.

Application filed October 2, 1914.. Serial No. 864,618.

To-aZZ whom it may concern Be it known that I, J GROVE BROWN, a citizenof the United States, residing at Groton, in the county of Tompkins and.

prises an endwise dumping vehicle, useful for general purposes, buthaving the body portion especially designed for the delivery of materialinto distributing attachments, and for the convenient connection of suchattachments, togetherwith an attachment adapted to be applied to saidbody and including a distributing roller, driven=by the vehicle, forthrowing the material against a baffle plate from whence the materialdrops down in a thin stream 'upon the roadway. v

In the accompanying drawing, which illustrates my invention, Figure 1 isa side elevation, with one of the Wheels removed, of .the rear portionof'an endwise dumping vehicle having my improvements thereon; Fig. 2i's'asimilar View, the wagon body and attachments thereon being shown incentral section, the wagon body being in dumping position; Fig. 3 is asection onthe line 33 of Fig. 1; and Fig. 4 is a rear-perspective viewof the distributing'attachment.

Referring to the drawing, a indicates the vehicle body, and b therearwheels. The

body is suitably mounted to dump rearwardly upon legs 1,,pivoted,at 2,near the rear. axle 3. The sides \4 of the body flare outwardly and,upwardly over the wheels, as indicated at 4?, and the rear ends of thesides flare outwardly, as indicated at 4, (Fig. 3) and are then turnedforwardly in the planes of the wheels, as indicated at 4. Therear endofthe bottom 5 also flares outwardly, as indicated at 5, the purpose ofthis flaring end of the body being to cause the material to spreadoutwardly in a .stream of greater width than the major portion of thebody as it leaves the vehicle and enters the distributing casing 0. An

angle bar 6 is secured at the sides of the vehicle and passes downwardlyalong the forwardly turned parts 4 and beneath the floor of the vehicle,strengthening the flarlng end thereof, and also affording a convenientstop and attaching means for positioning and securing detachabledistributers, chutes, etc., to the vehicle body. At the end of thevehicle body is arranged a slidmg and swinging gate cl, having at itsopposite edges vertical rack bars 7 (one of which is shown in Fig. 2)engaged by spur gears or 'PIHIOIIS 8; which are secured to a shaft 9journaled in suitable bearingsat the end of the body. This shaft isfitted with aworm gear 10 which is engaged by a Patented May 9, 1916.

worm 11, mounted upon an operating'shaft 12 extending toward the frontof the vehicle. It will be evident that by the opera tion of the shaft12, the end gate may be raised or lowered; also that the gate may swlngabout the shaft 9 as an axis unless the lower end of the gate is,restrained against this swinging movement. The vehicle as thus fardescribed issuitable for general purposes, without. further attachments,and may be used for hauling and dumping loads of material in piles oruneven: layers, although the body and end gate are. designed moreespecially for interchangeable attachments'for spreading the material ineven layers upon theroadway.

The distributing casing 0, shown in the drawing, comprises two similarends or heads 13, having flanges 13 provided with bolt. holes 13?through which'bolts 13 (Fig. 1-) may be passed to secure the heads tothe vertical portions of the angle bar 6 on thebody. These heads, whenin position, project rearwardly beyond the end gate. Journaled in theheads is a shaft 14 carrying a vaned distributing roller l5,'the rollerbeing positioned so that its vanes pass close to the rear edge of thebottom ofthe vehicle body. As shown in the drawing, there are four vanes15 upon theroller The casing comprises an upper wall 16, secured to theheads 13 at the rear of the end gate and extending downwardly andrearwardly" therefrom, forming a baflie plate, and a lower wall 17, alsosecured to said heads, this lower wall extending downwardlyconcentrically with the axis of the distributing roller through an arcof approximately ninety degrees from the rear end of the bottom of theallpositins'of the wagon body.

In'operation, when the vehicle 1 distributing gravel and fine stonescreen- 'ings, =the screenings distributer' attachment is applied to thevehicle body by fitting the heads'of theattachment .tothe angle bar'tiv'ticalliy. 'call'y to vary' the flow of material into, the .distributercasing, and when the *wagon {body is tilted andlthe-wagon'movedforis'open-between the guard 17 and the lower forms a "deflectorfor'the, materia1,-aS ibis thrown from the-roller: Upon the heads of the.casing are mounted brackets 18, to

which are attached rollers 19, which, when. the attachment upon the"vehicle, serve as guides for the gate in the vertical movefments of thelatter,' and' also restrain {the swinging movement of the gate;

The distributing roller is operated by;-

' means of a sprocket wheel 20,"'attache'd' to the hub of one ofth'e'vehicle wheels, a

sprocket chain 21 connecting said sprocket wheel with a smaller sprocketwheel 22, upon a shaft 23 which is journaled in been.

in'gs in one of the heads-l3. This shaft car-' ries-a gear 24, meshingwith' a. gear 25 on the roller shaft 14. By means. of a' suitable'clutch 26, ('Figml) the details of which are not shown,- the gear 24 maybe connected to or disengaged from the shaft 23 when. de-;

sired in order that thedistributing roller may be operated in dumpingthe load and stopped at other times An-idle roller "27,

upon a bracket 28, is suitably vpositioned for keeping'the sprocketchain or belt 21 taut in f and, bolting it thereto, and in this positionof the distributer. casing, the rollers 19 thereon restrain the end gateagainst swinging motion but permit the gate to slide ver- The gate maybe'adjusted vertiward, the material will flow, into thei casing and thedistributing roller willbe rap-' idly revolved, the vanes of the rollercausing f the material to be thrown against the rear; wall or deflectorplate 16, from whenceiti will drop downwardly on to the road. {Thef'arrangement of the distributing roller with reference to the openingbetween the gateand the floor of the body is such that if the wagomstopswhile the gate i s open, the

roller, then stationary, will Tchelck the floW:- of material andpreventit from being,'dis-' charged' on to the roadway. It is desirable,-'while the roller is ,in operation, to fill the" pockets formed betweenconsecutive vanes asjthey' approach and pass the outlet opening betweenthe gate and the floor of the body, in order that the materialmay be delivered on the roadway in an even layer, and it is'also desirable toprevent anyof the material whichpass'es over the top of the roller frombeing carried around. by the vanes as mightoccur at. slow speeds withsome classes of material. For these purs used for-f of the casingislmade short, from top to.bot-

I poses, curved portion of the end wall edge-16 ofthe wall 16, whichlatter wall tom,'-so as to give the material ample time to'dropyofi ofthe roller before the vanes commence their upward. movement.

. The length of this curved portion "should not, however, be less .thanthe distance between-- two vanes, as "the material commences to flowdown into the pocket p'betwee secutive vanes, to fill the pocket, assoon as one vane leaves the upper endof the curved. portion of the-part17 ofthe casing, and if this part were much shorter than the di'stance'between the vanes,';there would be a continual leakage of material pastthe rear side of the roller.

The Wagon y, withv its fiaring end sliding andswinging gate, a asstated; is use-.

in]; for general purposes, but .is particularly designediioi" use: inconnection with various forms, of distributing attachments of myinvention, in some of whlch 'thegate. is

givena sliding-movement only, and in others, a'swin'ging and slidingmovement: For i the purpose of thepresent 'invention,-; the

sliding {movement only is "desired and by providing the guide rollersupon the casing.)

of the distributing attachment, theplacing of the attachment inposition. against the angle bar 6 also locates the rollers in-.position'to hot as-guide rollers for the gate.
